[0006] The multi-functional interface module is electrically connected to the core main control unit module. The multi-functional interface module is internally equipped with an analog input interface, a digital input / output interface, and a CAN bus interface. The core main control unit module is electrically connected to a power management module for powering all modules.

[0008] As a preferred embodiment of the multifunctional integrated data acquisition box of this utility model, in order to better transmit data, the multifunctional interface module includes at least one of RS232 interface and RS485 interface, the wireless communication module includes a 4G communication unit or a 5G communication unit, and a GNSS positioning unit.

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0020] like Figures 1-3 As shown, this embodiment proposes a multi-functional integrated data acquisition box, including a core main control unit module 3, as well as a multi-functional interface module 4, a power management module 5, a storage module 6, a radio communication module, and a housing;

[0021] like Figure 2As shown, the multi-functional interface module 4 is electrically connected to the core main control unit module 3. The core main control unit module 3 uses a high-performance ARM-Cortex-A series industrial-grade microprocessor or multi-core microcontroller as the main control chip, serving as the "brain" of the entire integrated device. It is responsible for scheduling between various systems, data processing, protocol parsing, and edge intelligent algorithm execution. The multi-functional interface module 4 is equipped with analog input interfaces, digital input / output interfaces, and a CAN bus interface. The analog input interfaces provide multiple high-precision, programmable analog input channels, supporting various standard signals for connecting sensors such as pressure, temperature, and displacement. The digital input / output interfaces provide multiple opto-isolated DI / DO channels for acquiring switch status, alarm signals, and controlling relays, indicator lights, and other devices. The CAN bus interface provides a high-speed CAN bus channel for seamless data exchange with other control units such as the engine ECU, pump controller, and instrument panel on the rotary drilling rig. The core main control unit module 3 is electrically connected to a power management module 5, which supports DC 9-36V. The core main control unit module 3 features a wide voltage input to adapt to voltage fluctuations in engineering vehicle batteries. It incorporates multiple protection circuits against reverse connection, overvoltage, overcurrent, and surge. Simultaneously, the main control unit monitors the vehicle's ACC (ignition) signal. After the vehicle is turned off, it automatically enters a low-power sleep mode, maintaining only basic communication standby to extend battery life and powering various modules. The core main control unit module 3 is electrically connected to a storage module 6, which has built-in large-capacity solid-state storage and is equipped with an eMMC or industrial-grade SD card for caching temporary data, ensuring data integrity during network interruptions. The core main control unit module 3 is also electrically connected to a wireless communication module supporting FDD-LTE for transparent remote data transmission. It integrates a positioning module supporting the BeiDou multi-satellite system for precise vehicle positioning and trajectory tracking. The core main control unit module 3 collects various types of engineering machinery data through the multi-function interface module 4, processes the collected data, and uploads it via the wireless communication module. The housing is encapsulated on the outside of the core main control unit module 3, multi-function interface module 4, wireless communication module, and power management module 5.

[0022] It should be noted that the device's strengths lie in its highly integrated hardware, intelligent software processing, and environmentally adaptable structure.

[0023] like Figure 2As shown, the core main control unit module 3 is used to filter and unify the format of the collected raw data, and to provide a preset data change rate threshold to adaptively adjust the frequency of data acquisition and uploading. At the same time, the time-series data is compressed before data transmission. The multi-functional interface module 4 has at least one of RS232 and RS485 interfaces. The wireless communication module includes a 4G communication unit or a 5G communication unit, as well as a GNSS positioning unit. The storage module 6 is used to cache data when the network is interrupted. The power management module 5 is equipped with a wide voltage input circuit and an intelligent power management unit, supporting an input range of DC9-36V. The intelligent power management unit is configured to switch between normal mode and low-power sleep mode in response to the status of the external ACC signal.

[0024] like Figure 1 As shown, the housing is made of a high vibration resistant material and includes a lower housing 2, an internal support frame, and an upper housing 1. The bottom of the lower housing 2 is flexibly connected to the external mounting surface through an elastic damper. The internal support frame is set inside the lower housing 2 through multiple elastic buffer elements. The upper housing 1 and the lower housing 2 are fixedly connected by bolts and nuts. A circuit board is set on the internal support frame. The core main control unit module 3, the multi-functional interface module 4, the power management module 5, and the storage module 6 are all fixed on the circuit board through conductive pins and wrapped with thermally conductive potting compound.

[0025] In this embodiment, during the startup phase: the vehicle battery is connected to DC9-36V voltage through the side interface of the lower housing 2. The power management module 5 completes voltage conversion and multiple protection detections. After detecting the ACC high level, it supplies power to the core main control unit module 3, the multi-function interface module 4 and the storage module 6. The system starts up and loads the embedded Linux system in the core main control unit module 3. The entire startup process takes ≤3 seconds.

[0026] Data acquisition and processing stage: Analog / digital sensors and engine ECU are connected to multi-function interface module 4 through the side interface of lower housing 2, and upload data to core main control unit module 3. Core main control unit module 3 completes protocol parsing and edge algorithm processing (such as fault judgment). When the network is normal, the data is uploaded to the cloud through the wireless module of multi-function interface module 4 and stored in storage module 6 at the same time. When the network is interrupted, the data is only stored in storage module 6.

[0027] Sleep and wake-up phase: After the vehicle is turned off, the ACC signal becomes low level. After the power management module 5 counts for 5 minutes, it shuts down the wireless communication and analog signal acquisition functions of the multi-function interface module 4 and the unnecessary power supply of the storage module 6, and only maintains the basic standby of the core main control unit module 3 (power consumption < 5mA). When the ACC high level is detected again, the power management module 5 wakes up all modules within 1 second and enters full-function mode.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
